STEAM-PUMP.

SPECIFIC-1.51116 inf-'forming part of Letters Patent No, 362,762, dated May 10. 1887.

- Application filed Jnnu:\r G, ISST.

To all whoml it may concern:

Beit known that l, .Tous M .vnna, offlast Hampton, county of Hampshire, and State of Massachusetts, have invented new and useful Improvements in Steam-Pumps; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consists in a certain specific construction of parts for moving in a simple manner the auxiliary valve of a stenni-puinp, as will be fully described hereinafter.

1n the drawings, Figure' 1 represents a side view of a pump having my invention applied` thereto, and Fig. 2 an end view of the same.

To enable others skilled in the art to malte my invention, I will proceed to describe fully theV construction of the same.

1 represents a base-piece of :my proper construction.

2 represents a fixed standard rising from the basepiece at the center of the same, which standard is rigidly bolted or otherwise secured to the hase-piece at the lowerend, and is provided with a jonrualbearing, 3, as shown in Fig. 2.

4 represents the piston-rod of the pump, and 5 a block centrally secured thereon at the proper point, the lower arm, 6, of which is provided with a proper opening, in which is held the shaft 7, as shown.

S represents au actuating-arm, having below a forked portion, 9, adapted to receive the shaft 7 ot' the block 5, and above a pivot-shaft, 10, which is held in thejour-nal-bearing 3.

11, Fig. 2, represents a nut by means of which the pivotshaft is properly secured in place.

Serial Xo. 223,514. (No model.)

12 represents a stud projecting from the face ofthe actuating-arm next the valve-rod, as shown.

13 represents the rod of the auxiliary valve, supported at its outer end in any proper mauner.

14 14 represent adjustable tappcboollars located on the valve-rod at the proper point, and 15 a spoot of ordinary form loosely held on the valve-rod between the tappetscollars, as shown.

"hcn the parts arc in their proper relative positions, the stud l2 upon the actuating-arm S extends between the shoulders of the spool, as shown.

The operation is :is follows: By the movement of the pistonrod carrying the block 5, the actuating-arm S is swung upon its pivotshaft 10 from one end of the stroketothe other, and its stud is consequently caused to move the spool l5 into contact with the proper tappetcollar. By this means the valve-rod is actuated in the manner well understood.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent. is"

The combination of the lever S, having the stud projection 12 formed thereon in line with the center ofthe valve-stem 13, this vaive- Stem having the tappet-collars 14 14, and the loose spool 15, adapted to revolve freelyon the valve-stem, as described.

This spccitication signed and witnessed this 22d day of December, 1556.
